DETACHABLE SHELF-BRACKET.

Specification of Letters Patent.

Patented Sept. 5, 1905.

Application filed September 16, 1904. Serial No. 224.661.

Be it known that l. Jol-IN Kinn'unxx, of Toledo, county of Lu as, and State of Ohio. have invented certain new and useful Improvements in Detachable Shelf-Brackets; and .I do hereby declare that the following' is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to mak? and use the same, reference being' had to the accompanying' drawings, and to the characters of reference marked thereon, which form part of this specification.

My invention has reference to a detachable shelf-bracket; and it has Vfor its object to provide a simple, inexpensive, and durable sheetmetal support for a shelf capable of convenient and instant attachment or detachment Vfrom a wimlow-sill or other place where it may be employed.

ln carrying out my invention l employ the novel combination and arrangement of the parts hereinafter shown, described, and claimed.

ln the accompanying' drawings, Figure l is a perspective view showing' a shelf detachably mounted upon a \\'imlo\\'-sill, the same embodying my invention. Fig. 2 is a sectional elevation illustrating' in dotted lines the operation for detaching the shelf. Fig. 3 is also a sectional elevation showing a slightly-modified form of attaching-plate, the same being' adapted Vfor employment upon porches or other places where the attaching-plate may be sccured by means of screws.

ln the preferred embodiment of my invention lV employ a bracket stamped out of sheet metal having' a triangular-shaped body l, the central portion thereof being cnt ont, as indicated at 2. The forward. inclined edg'e portion 3 and the top edge portion of the body are bent sharply at a right angle to sti l'l`en and strengthen-the same, providing' an extremelyrigid support for the shelf 6, the portion -i being' provided with perforations to permit of fastening' the shelf to the bracket by means of screws, and the lower end of the portion is extended at o to contact with the wall below the shelf when the latter is in position and provide a lirm support for the same. rlhe extended portion o" being' of sheet metal not strengthened by ribs or otherwise, may be readily bent to adjust the shelf in trne horizontal position. The portion l is also extended rearwardly, as at 5l, and the extreme end is bennes indicated at T, to enter and engage one of a plurality of spaced transverseslots S,

' provided ina vfastening-plate 9, also constructed of sheet metal, the side margins ot' which are bent downwardly. as at 10, to raise the central portion in which the slots are formed above the window-sill, thereby permitting' the convenient insertion of the bent end 7 of the extended portion i of the bracket. The fastening-plate at its outer end ll is bent downwardly at a rig'ht angle, taking a position when placed upon the window-sill between the outer face of the sill and the sash. The bent portion ll at its lower margin is provided with serrations 12, extending'inwardly to enter the sill, being' forced into the same by the sash as the latter is lowered. lt will thus be seen that the Vfastoning-plate is irmly secured in place without the employment of screws or other vfastening devices which would mar the finish of the sill exposed to view when the plate is detached. ',lo cause the top surface of the shelf when in position npon the brackets to lie in the same plane with the windowsill, the rearwardly-extended portion 5/ of the bracket is offset, as shown at 13, the window sill being lirmly clamped when the bracket is in position between said offset portion and the serrated portion of the fastening-plate.

lhe operation necessary to fasten the bracket in position is plainlyindicated in Fig'. 52.. The slotted Vfastening-plate is lirst placed in position upon the window sill and the bracket is then held in angular positionwith relation thereto, as indicated in dotted lines if, to permit the insertion of the bent end of the extended portion 5 into one of the slots in the fastening-plate. Upon lowering' the bracket tothe position shown in full lines, Fig. Q, the same will be iirrnly held in place.

ln Fig. 3 is shown a construction adapting the employment of my improved bracket upon porches or other like places, the slotted fastening-plate being' secu red by means of screws, the bracket being detachably engaged in the same manner as herein described.

From the foregoing description the novelty, utility, and manyadvantages of my invention will be apparent.

Having' described my invention, what I claim, and desire to secure by Letters Patent, is4

l. 'ln an article of the class described, a sheet-metal bracket having' the top marginal edge portion thereof bent angnlarly and having said bent portion extended rearwardly and bent at the end, and a slotted plate adapt- TOO ` stantially as described.

3. In a device of the class described, a sheetmetal bracket having the top and forward marginal edge portions thereotl bent angularly and having the top angular portion extended and bent at the end and provided with an offset adjacent to the body of the bracket, and a sheet-metal plate provided with a plurality of spaced transverse slots adapted to be engagedv by the extended portion of the bracket, said plate being bent angularly at its outer end and provided with serrations along the lower margin of said angular portion, substantially as described.

In testimony that I claim the foregoing as my own I aiiix my signature in presence of two witnesses.

JOHN KETTEMAN.
